FREDERICK JOSEPH HADFIELD, OF RING-SFIELD, BECCLES, ENGLAND.

Application filedlannary 8, 1914 Serial No. 810,958.

To cllwhom it may concern:

Be it known that I, FREDERICK JOSEPH Britain, residing at Manor House, Ringsfield, Beccles, in the county of Sufiolk, England, engineer, have invented certain new and useful Improvements in Wheels, of which improvements the following is 'a specification, reference being 'had therein to the accompanying drawing.

This invention relates to improvements in adjust-able rims for the wheels of motor cars and other road. vehicles, and to pneumatic tires and tire covers for use therewith of that \type in which the tire cover is clamped between the rim flanges and a re-- movable inner band or'hoop by transverse bolts and nuts; and has for its object to greatlyiacilitatmthe removal, replacement afid fixing of such tires, tire covers and inner tubes both asa whole and separately while considerably augmenting-the strength and efliciency of the rims and tires or tire covers and inner tubes as a whole.

' According to my invention the adjustable 1 wheelrim is formed of a double box girder section which is transversely stayed and gcomprises an outer rim having a detachable j.side, and a loose inner supporting ring both of which are of achannel cross-section, while the tire-or tire-cover for use therewith is formed with a flange or flanges of rubber.

and fabric, or the like, on one, or'on both sides, so that the same. can be clamped between one or both sides of the outer rim andthe inner ring by means .of transverse bolts and nuts, the bolts passing through :the sides". of the outer rim and of the inner ring and also'thrpugh suitable sleeves or distance pieces which are arranged between removableinner ring rest upon the bottom ,of the outer rim, .while such-inner ring is shaped and dimensioned so as to form a seating for the tire and the inner tube, and likewise to leavea space on. one or both sides for the compressible flange vor flanges of the-tineto pass between such ring and one orlhothsides of the outer rim. The detachde'of the outer rim is grooved so as to the'bottom of such rim and is secured "5 b thetransverse bolts and nuts which likewise serve as additional fastenings to sesponding parts.

Specification of Letters Patent. Patented May 19, "1914.

j cure the ti reto'the riniand so dispense with the ordinary security bolts. The tire 'or tire cover is headed in the ordinary manner so as'to engage with the usual groovesor .recesses in the outerrim, while the inflating tube, which may be made rather longer than usual, asses through apertures 01": the usual shape 'ormed for the purpose in the inner ring and outer rim..

My invention is further described with the aid of the accompanying drawings, Figures 1, and 2, being transverse sectional views illustrating alternative constructions of my improved 'rim and tire as applied to a wire wheel; .while Fig. 3 is a. side view f the same with parts brokenaway,

Similar reference numerals indicate corre- 1, is the outer rim having a detachable side, 2, and 3, the loose inner supporting ring, which outer rim and inner ring are bothof a'channel.section,4, is the tire or tire cover having a flange 5. of rubber and fabric, on one or on each side,6, is the'inner tube of the tire, the usual inflating'tube and valve not being shown.

7, indicates the transverse bolts, which are furnished with nuts, 7, for clamping the several members of the rim and the tire firmly together; while 8, and 9, are trans verse sleeves for staying the rim through which sleeves the bolts 7'. pass. The inner ring 3, is made narrower than the outer rim, 1, so that when placed in position on the latter suflicient space is left on one or on both sides of such ring for, the reception of the flange or flanges 5, of the tire or tire cover. The edges of the inner ring rest on the bottom of the outer rim as shown, while such ring is shaped so as to afl'ord-a seating for the tire or tire cover, 4, and for the inner tube 6. The inflating tube is made ders 8, formed on such sleeves which shoal-- ders, engagev with perforations in such cheeks; while the sleeves 9, are arranged between the sides of the outer rim and the inner ring as shown, and pass through suitable slots or holes formed in the flanges 5, of the tire or tire cover for the passage of the sleeves and bolts.

If preferred the sleeves 9 fitted at the back of the rim may be recessed into or brazed to the same and the front ones may bein like manner secured to the detachable side 2, which is formed with a groove 2,

so as to clip the bottom of the rim as shown, while such loose side also engages-with the ordinary beading on one side of the tire, and is firmly secured and stayed transversely by means of the trans erse bolts and sleev I In the construction shown in Fig. 1, th tire or tire cover 4, is furnished with a flange 5 on one side only, such flange being formed of rubber and fabric while the'inner,

so that such flanges can be clamped between both sides of the rim and the cheeks of the inner ring. In both arrangements the rim and tire are firmly secnred and stayed by tightening up the nuts 7 which compress the flanges 5 of the tire 4: between the sides of the enter rim endinner until the thrust is taken by the sleeves 9, and theninflatlng the air tube the nuts being locked in position in any preferred manner. In"

the double flange arrangement the tire may he firmly secured without inflating the air tube.

What I claim is:-

In combination with a the, a ring having a concaved portion to form a seat for the tire and fn'ovided with a pair of flanges, a time having a rigid side formed with a tire engaging portion, a removable side engag ing the rim and formed with a tire engaging portion, and means for clamping the ring and rim'upon the tire, said means consisting of sleeves passing transversely through the ring and sides of the rim, and a clamping bolt mounted in said sleeves.

In testimony whereof I afi'ix my signature in presence of two witnesses.
